The camp mainly and PLing peeps. At that PoD camp, if you make your kiting area larger, you get more spiders and back then, they could DoT me to death in a hurry.
Gearing and AAs are a factor too. Can't quad ice burrowers until you have basically ER, SH and the Quick Damage AAs done. I forget the exact numbers, but when I first tried with no Quick Damaga AAs or Extended Range or even Spell Haste, they'd be beating on me before the spell finished casting. Eventually as I added ER, I think I could just land a spell and run away without being beaten on some of the time. Then I added in the Quick Damage AAs, followed by 15% spell haste and they made a night and day difference. That was 7 years ago, took about another year to get all the right class IV focuses. Stopped shortly there after quadding them as well as quadding ice burrowers and high speed kiting named in WW just isn't that much fun, mainly a lot of stress. (Basically they're impossible to snare, a druid or ranger might bother as if they land it, it'll last 15 minutes, but a wizard's is so short as to not bother.)
I guess I approach it a bit differently, my experiences started when no one had focus items. Everyone pestered mages to no end for the summoned ones, Bastette left corpses to save them between logins, it really became having a spell that could hit with reasonable damage in a quick time and run speed differential. Once you're 65 and have all your spells, it's then just run speed differential.
